Welcome to the forum Sairadance, lovely to have you. I haven't much to add, everyone has given you solid advice. There really aren't any easy answers. PTSD is a very difficult illness to deal with, many ups and downs, even once the sufferer has reached a management stage. For example, my daughter has done exceptionally well with her recovery, however the past day or so has been most ill once more and in bed due to the PTSD. There is not much my husband and I may do except support her, be there for her if she needs us and "ride out the storm" so to speak. Day to day relating has largely been a trial and error process for us. Have you read the Carers Information section? I suggest that as a place to start, there are several good articles and suggestions. Arm yourself with knowledge as that will be your best defence in dealing with this illness. Take care and welcome once more.
